Post by cgokan » 2020/01/06 07:42:24

Hello

I received an error like the following. I have two servers running on KVM. One is the database and the other is the application server. How can I solve this problem?

Start by running yum update and getting up to date. That kernel is from 7.6 which was superceded by 7.7 from August last year.
The future appears to be RHEL or Debian. I think I'm going Debian.
Info for USB installs on http://wiki.centos.org/HowTos/InstallFromUSBkey
CentOS 5 and 6 are deadest, do not use them.
